Did the job for our campaign. Dedup pass only flagged 1.2% — cleanest dataset I've worked with. Bought it as part of a wider gift shop expansion into Poland. One column I'd add next refresh: secondary email.
Appreciate the write-up, noted on the minor gaps — they're tracked for the next refresh. If you want the gaps fixed sooner than the next refresh, open a support ticket and we'll spin a one-off pull.
